Description of the Invention: [Technical Field] The present invention relates to a method for waking up an electronic device and an electronic device, and more particularly to a new support A wake-up method for adding or removing electronic devices of a non-hotplug device. [Prior Art] In the Advanced Configuration and 〇P〇ww Interface (ACPI) standard, the state of the computer system includes a sleep state that consumes less power (sleeping) in addition to the working state so (sleeping) Mode). According to the power consumption and the recovery speed, the sleep state can be divided into several levels such as S1, S3, S4 and S5. In the state of sl (p〇wer 卿end), the computer system only shuts down the screen, so it can quickly return to the working state. ❿ In what is called memory sleep (called (four) secret state] except the memory and its controller need power to protect 1 ^ f 'the rest of the device is powered off. S4 (suspendt0 disk) shape 1; Hard disk, so no longer need to supply power to the shutdown state, at this time _ non-return to the working state requires S5-like energy, brother 'the most power-saving in the above-mentioned dormant state · this wheel into the output season system (B "Return to the working state, you need to open the white ring, 糸, first Basic Inpm 〇utput System, BIOs) Description: =M to initialize and sweep the peripheral hardware device and fill the phase_set value to The peripheral hardware device, until 200923784 ... Jtwf'doc/006, completed the corresponding booting secret after completing the corresponding green drive. The execution of the above actions will cause the startup time of the computer line to become very lengthy. :: Below, due to the computer Before entering the S3 state, the system has recorded the current recording conditions (including various settings, drivers, or the status of the application being executed) in the page slot (page Ο ^ and will store the minutes (4) in the memory. So use When the computer system is restarted from the power saving mode S3 to the working state sq, only the titer output system is required to perform the basic wafer shape, and the main 2 notes of the computer system are handed over to the operating system to pass through the paging file. The computer is set to the original state. It can recover to the working sorrow at a fairly fast speed without any hardware initialization, scanning and _ actions, precisely because the computer system is composed of S3. The status returns to the working state. For example, the native input system will no longer scan the peripheral hardware devices. Therefore, the financial users add or transfer any non-hot plugs under the S3 wire. When the device is regained to the working state so, the actual state of the hardware device is not good, which will cause the computer system to crash, and if it is serious, it will be damaged by the computer system or hard property. That is to say, if the user wants to be able to quickly start the computer system, he or she will be set to 8 to remove or remove any non-hot plugs in the state of = 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 ), Wei User I is in power When the device enters the memory sleep (S3) state, it is still 200923784. Jtwf.doc/006 can add or remove any non-hot plug (n〇n_h〇t_plug) device without causing the electronic device to crash or be damaged. It is impossible to restore the work, thereby increasing the convenience of the use of the computer system. The present invention provides a wake-up method for an electronic device. When the memory is in a sleep state, when waking up to a working state, the user is first judged to be in a memory sleep state. Whether any non-hot plugging device has been added or removed, and according to the judgment result, the __ program is not executed, and the non-hot plugging device is added or removed from the (4), and the computer system cannot be normally turned on. . The present invention provides an electronic device having an active state and a memory dormant state, and is coupled to at least one non-hot plug device. The electronic device includes a detecting circuit, a storage unit, and a sense module. When the circuit = 任: non-hot plugging device - change state, the output - state change value. , storage unit New · stored state change value. t 抒 When the sleep state is to return to the working state, if the power-on module detects _^, the electronic device performs a normal booting procedure. The change state of the non-hot plugging device is that the non-hot plug F is mounted on the electronic device and one of the non-hot _ is removed from the electronic device. If the boot module does not detect a status change value, " a memory sleep reply procedure. "The device performs a normal boot process, including the use of a parameter in the memory for the non-hot plugging and resetting the sleep reply program. The memory is restored to the working state by the memory." In an embodiment of the present invention, the detecting circuit includes a unit and a logic gate, wherein each of the detecting units is detected in the morning, and the measuring unit is 200923784 ----------"twf. Doc/006 One of the non-hot plugging devices, when there is this change state, corresponds to the output signal. After the logic gate receives the signals, the state change value is output. The logic gate can be a NAND gate. The detecting units are respectively disposed in the plurality of non-hot plugging device slots to control the signal output according to the electrical connection between the non-hot plugging device and the non-hot plugging device slot. In an embodiment of the invention, the non-hot plug device includes a memory, and the electronic device further includes a memory power switch. The memory power switch is connected to the memory, the detecting circuit and the power source to cut off the power supplied to the memory when the detecting circuit detects that the memory is added or removed. In one embodiment of the invention, the storage unit can be implemented in either a South Bridge wafer scratch or a Super I/O wafer register. The boot module includes a basic input/output system (Basic inpUt/〇utpUt System, BIOS) and an operating system. The non-hot swap device can be an Integrated Drive Electronics (IDE) device, a Peripheral Component Interconnect (PCI) device, or a PS2 device. 〆I ηκ ^ " From another point of view, the present invention provides an electronic device wake-up method electronic device suitable for configuring at least one non-hot plug device, the method package, although detecting any non-hot plug device When one changes state, it produces / cancer and changes the value. Store the status change value. When the electronic device is returned to the active state by the memory sleep state, if the state change value is detected, the electronic device performs a normal boot process. The present invention records whether the user has added or removed any non-hot plugging device when the computer system is in the memory sleep state. According to this, in the 200923784 --------.itwf.doc/006, when the computer system returns to the working state, it can be judged according to the results of the record, and it is necessary to use the § recalled sleep recovery procedure or the traditional Start the program to respond to the computer system. Therefore, as long as the user does not add or remove any non-hot plugging, the computer system can return to the working state through the memory sleep recovery procedure, thereby speeding up the startup of the computer system. The above described features and advantages of the present invention will become more apparent from the following description. p [Embodiment] In today's computer system architecture, the memory sleep (S3) state returns to the working state, which is both power-saving and fast startup mode. However, the new banding or removal action of the non-hot plugging (n〇n_h〇t_plug) device is not supported in the S3 state. Therefore, if there is a mechanism to record the state in which the non-hot plugging device is added or removed in the S3 state, and then the electronic device (or computer system) is restored from the memory sleep (S3) state to the working state. According to the measured non-hot plugging (n〇n_h〇t_piUg) device change state 'to select the program to start the electronic device, it is bound to be able to directly update without any 'non-hot plugging device' Speed up the startup of the computer system through the memory sleep recovery program, and avoid the crash when there is a change to the non-hot plug device.

The computer system in the S3 state, wherein the electronic device (10) includes the _ circuit 110, m and the boot module 140. In the embodiment, the computer system can be configured with a plurality of non-plugging (:=plugging, non-hot plugging device 123 and non-hot plugging device U5), the non-hot plugging device can be Hard drive, mouse, or video card. To distinguish it from the computer's pure interface, non-hot-swappable devices include integrated drive electronics ((4), Eiectronies, ship), periphemi Component Interconnect (pCI) devices, or ps2 devices. Etc., there is no limit to its scope here. The detecting circuit 11 is configured to detect the changed state of the non-hot plugging device, and is connected to the storage unit 13A, and then stores the state (change) value output according to the changed state to the storage unit. 130. Further, the detecting circuit 11 includes a plurality of detecting units (for example, detecting unit 111, detecting unit 113 and detecting unit 115) and a logic gate 117. In this embodiment, each detecting unit is used to measure the state of different non-hot plugging devices, and when the state of the corresponding non-hot plugging device is updated, the corresponding signal is rotated. For example, when the detecting unit 111 detects that the non-hot plugging device 121 is added or removed, the logic gate 1 outputs a signal indicating that the non-hot plugging device ι21 is updated. In one embodiment, the detection unit in the detection circuit 110 is, for example, disposed on a non-hot-swap device slot of the motherboard. Taking pC][slot as an example, a detection list 200923784 twf.doc/006 is set on all PCI slots of the computer system motherboard, and the detection unit will be based on the connection relationship between the PCI slots. The number of the device (10) and the PCI device is determined. For example, suppose that the PCI device is connected and outputs a corresponding signal to output a high-potential signal. Then, the Ρα loading on the alpha slot of the mailing is as follows: when the original mobile phone is moved, the fr: the value of the signal of the output signal will be changed to be set in the case of 'Best in the computer system. Early detection, and the detection unit is, for example, based on the t-pins of the p-pins, or the slot (ϋ). It must be emphasized here that the above only: whether the line is updated and the input == = test =: = the invention described in the invention, and the signal output by the debt measurement unit Will be - Γΐ = 17 input, where logic 117 can be achieved, for example. After receiving the above signal, the logic gate 117 generates a corresponding state value for all the signals of the two, and transmits the value to the storage unit (10) through the === value. The logic gate 117 is in the state of all non-hot plugging devices. in other words, . The state of the non-hot plugging device is changed, which causes the corresponding signal to be output, and the damper value of the logic gate 117 is changed accordingly. That is to say, 'when any non-hot plugging device's grievances are changed', the secret value stored in the storage unit m will also be changed according to 11 200923784 3twf.doc/006. In this embodiment, the storage unit 130 for storing the state value is, for example, a south bridge wafer register or a Super I/O chip register, and the scope is not limited herein. c The boot module 140 is connected to the storage unit 13A and executes a different program depending on whether the status value is changed or not, and then returns the computer New & Memory Sleep (S3) state to the active state. The boot module 14 is, for example, a basic input/output system (Basic jnput/〇utput Systejn, Bi〇s) and an operating system. The following embodiment shows the detailed steps of how the boot module 14 starts the computer system based on the status value. Referring to FIG. 2, when the user wants to return the computer system from the memory sleep (S3) state to the working state and press the power button, the first step is as shown in step 21, and the boot module can just use the basic input. The output system reads the status value stored in the storage unit 13g. Next, in step 220, it is judged whether the state value has changed, or is originally - set value ' and then has received a state change value different from the setting. If the (4) front is unchanged (or the original, set value), the face user does not add or remove the device in the S3 state. Therefore, as shown in step 230, the boot-to-memory sleep recovery procedure can be used to re-load the user in the computer system to enter the S3 state secret bribe to the fourth parameter - (four) (ie, the page slot fllej). According to this, the computer system can be quickly restored from the % state to the working state.戸 However, if the power-on module 14 determines that the status value has changed _ the user may be new = some #hot-plugging device while the computer system is in the S3 state. In order to successfully start the computer system and use ^ 12 200923784 twf.doc / 006 heat-inserting device 'as shown in step 240 'boot module (10) will be the second, the normal boot process 'that is through the boot self-test ( P〇wer 4 newly scans and sets the hardware devices of the computer system (including all non-,,, and plug-in devices). The devices thus added can be operated after the initializing operation. In the 25G, the operating system is carried to the computer system to complete the entire reply process, and then the computer system is put into the state of the security to receive the use of the user. Since most users do not often do it each time. Add or remove the miscellaneous plug-in device before using the computer system. Therefore, in the case of the boot module 140, the system will execute the memory sleep reply program to restore the computer system to the working state. Compared with the traditional boot The program, the memory sleep response sequence takes a relatively short time, so it can speed up the speed of starting the computer system', thereby improving the efficiency of use. In addition, the user can still be in the S3 state according to the demand To add or remove non-hot plugging devices without feeling the inconvenience of not being able to update the non-hot plugging device under the traditional S3 state. It is worth mentioning that the memory used to store the paging file in the computer system (For example, dynamic random access memory, Dynamic Rand〇m eight memory ^ Memory 'DRAM) is also a non-hot plug device. When the computer system is in the S3 state, 'in order to save data must be supplied to the memory. To avoid using In the present embodiment, the memory is arbitrarily inserted and removed to cause memory damage. In this embodiment, the power supply to the memory is managed. Referring to FIG. 1 'For convenience of explanation, it is assumed that the heat is not hot in this embodiment. The plug-in device 125 is a DRAM. In the electronic device 1 , the memory power switch 150 and the non-hot plug device 125 (ie, DRAM), respectively, corresponding to the detection unit 115 of 13 200923784 ^f.doc/ooe DRAM, And supply to dra, the detection unit US detection is added or moved; in the original, the: memory memory switch 丨50 will be connected to the DRAM and power supply, the secondary circuit is disconnected to stop power supply to DRAM, according to this protection Damaged. In another embodiment, the function of the power button of the computer system is set to enter the S3 state by way of, for example, software implementation. Accordingly, whenever the user presses the power button, the computer system directly enters the phantom. Bear: The wake-up system that sleeps through the memory can detect the update status of the hot-swappable device in the S3 state, and judge the memory to sleep when the controller presses the power button again to start the computer system. The program or boot sequence is used to start the computer system. For the user, if there is no new or removed = what is not the hot plug device, the speed of starting the computer system will be greatly improved. The electronic device and the wake-up method thereof according to the present invention have the following advantages: > 1. A judgment mechanism is added when starting the computer system to confirm whether the non-hot plug device is updated. If the user adds or removes a non-hot plugging event, the computer system is booted using the traditional boot process. According to this, the user can update the non-hot plugging device according to the demand in the state of ^, and does not cause the crash when the computer system is turned on, thereby increasing the flexibility of using the computer system. 2. Quickly turn the computer through the Memory Dormant Recovery program if the user has not added or removed any non-hot plugging device. ... to work, which in turn increases the efficiency of starting the computer system to increase the convenience. ^ Π 14 200923784 3twf.doc/〇〇6 User's new or ageing mechanism, according to the mechanism of cutting off the power supply when the skin is isolated, to prevent insertion and removal under the condition of electricity Memory damage caused by memory.
